This is awesome!! It was great meeting you at FAR - can't wait to see more. Also nice job on the video too :)
This bloke, yourself, Tom Stanton's gas thruster quad copter, Xyla's materials science and design aesthetics,.... Got most of a Space Program right there!
Bro I just found this guy and it reminded me of you and here you are 😭
FAR -- Muslim brotherhood - half the time! SP' - Jap battel fleet - or in - your felon:
"SHIP < served u, in the - nazi attack raids!"
This is awesome - really well done!
It is fantastic to see BPS inspire others that will in turn inspire others. Nicely done!
Nice work, I clapped on each successful launch! Love seeing the improvements over time. Look forward to another project you share! Never stop building
Awesome flights! I'm a huge fan of your flight computer layout too :)
This is so sick. I came from your tiktok, very glad I did. I’m going to grad school for GNC in the fall and I work in GNC atm, so this is very interesting to watch. Excited to see what you do with this, you got a bright future ahead of you man
would love to hear more about the TVC and simulator development. I’m very interested in that part of rocketry. I’m a mechanical engineer by education, so haven’t had too much rocketry exposure and it’s always cool to learn about it
Have you considered modeling this in simulink? you can simulate the control system and tweak it there, as well as auto code it into C
Will definitely be looking into it!
@@KofiAsare0hell yeah man! it comes included in the student version of MATLAB, im sure your college has a license
Absolutely brilliant test of patience and determination. I’m excited to see what you have lined up in the future! I would think it would be fascinating to move to a larger scale to get more realistic and reliable telemetry data due to the overall mass increase. In addition a larger scale will allow you to see you more heat data, which will help you increase thermal efficiency, leading to longer flights. I am very intrigued with this project and approach to racketeering.
Congratulations for being persistent! :) I've had the idea to create such a system for my Engineering undergraduate project but it was much more complicated after a couple of researches :) Congratulations once again for making such a great job there!!!
Even as someone with very limited interest in rocketry - this was a must watch, and I’m excited for more. Personally I’d love to see a dedicated overview of the controller circuitry and its development process at some stage, but the general story of this project is absolutely fascinating…
Thank you so much for watching, next video will be all about the Flight Computers!
Yes CP and CG relationship is a crucial aspect in rocket flight stability.Great content.
I launched my first (Estes!) model rocket in 1975, went into I.T. years later, but never married the two. Seeing you take this to a whole 'other level blows my mind. Sincere thanks for sharing - I'm looking forward to future videos!
Such a cool video.
Great work with all the PID gains - I realise that it's not an easy task.
I subscribed to see the follow up videos you make.
Very cool. 👍👍Don't forget the freezing of the integration when the actuators are saturated (max throws).
Congrats on the persistence and resulting success! It's inspiring to see you kept at it over that time frame and eventually made it work - looking forward to your other projects :)
Awesome video. I'd be really interested to hear how you worked your way through the computer hardware and software design decisions.
More please - I really enjoyed your presentation and I'm already wanting to click on the next video. Great work!
Great job Kofi. I saw the thumbnail and the Channel name and was like holy sh*t, i must see this. 😂😂😂😂. Just subscribed. Hoping to see more from you.
This was really cool, but I had to playback at .75. First time I slowed down a video.
Super looking forward the details on the FC design.
Great work! I'd like to see more on software, especially what measurements you're getting from the MPU6050 and how you're integrating them into the control loop. Thanks!
The last lunch test was amazing it had very great stability good job!
Great work, really awesome efforts and results!
Nice job Kofi! Having talked to a variety of senior projects teams, it seems like designing an Avionics system, especially one with PID control, seems like an extremely challenging task!
Nice work mate, all the best for the future!
love this - super inspired now! thank you!
Kofi this is absolutely incredible!!! This is genuinely one of the coolest things I've seen someone do, and I'm so proud to be able to say I've worked with you :)
Duuuuude, great video and awesome explanations, thanks for sharing!
Love your design, keep going!
Congrats on your work getting here!
re: the flight computer software, huge kudos on your approach change (should I say "course correction"? :D ) between loop, RTOS, and then loop again. As a fellow engineer and now working with software, I know it takes a sizeable amount of focus and dedication to not fall for the sunken cost fallacy of "I've already implemented , I shouldn't just go back!", and recognize priorities in the wide sense!
It is beautiful quality.
You are tenacious; you will succeed.
Amazing. Can’t wait to see what you do next.
Incredibly impressive!! Keep it up man
Impressive stuff! Keep up the good work. It's not many recent HS grads who've made their own PCB & all the other things you've done - along with TH-cam documentation. You're going places, kid! Keep on truckin'.
Amazing work!
As am currently pursuing Bachelor's in Electronics and Communication Engineering, and I also designed my Flight Computer out of Raspberry Pi Pico RP2040 MCU and other sensors.. And since no idea about rocket motors, my Flight Computer just spending it's time laying around, and sometimes just records random data while sitting on RC quad coptor. 😢.. hopefully I'll make it work in an actual model rocket this year.
Impressive work and excellent presentation!
awesome iterative prototyping and test driven development
congrats and thanks for the detailed explanation 👍
Good job. This is a cool project.
Great job bro! Cheers from Brazil!
That is awesome! I'm definitely interested in seeing how you designed your flight computer, this is really nice work
awesome bro. passion and perserverence. keep going!
Awesome job. We need more!
TH-cam recommended this video. I'm really glad that it did. Great work!
Thanks for watching!
Please do a detailed video of how you built and programmed the flight computer, Great video!!!
Well done! Keep at it
Fantastic work.
Very cool, congrats!
Dude instant sub! This is so impressive
Really impressive!
Well done
Good work
Great channel and great project. You just earned an exited subscriber ;)
So cool!
This is excellent!
Great work! Nice touch using RTOS for firmware.
It's blokes like you and Joe Barnard who should be working on the Mars Sample Return project. You've accomplished so much here, at an enthusiast budget level, building skills and knowledge that will be invaluable to future human endeavors. Well Done!
"Joe" Barnard BPS Space, agree.
@@jeffrey5961 Dagnabbit! :)
Awesome video! I would love to see more about the coding process and how the electronics work together
You made that look easy.
Great job on the project! I would encourage you to record the overdub in a conversational tone, it can help a ton in conveying your excitement for your project. Keep up the great work!
This is incredible! So many different disciplines executed... how did you learn how to all of these skillsets so quickly?
Wow really good, amazing, as a programmer and designer from Hardware amazing work.
im hyped for this
I wanna see more !!!!!!!!!!! Nice video
Nice work !
Its very cool! Keep making videos! It would be great to see how is your rocket's computer works and how you did the PCB!
Thanks for watching, the next video will be all about Flight Computer ONE!
@@KofiAsare0 Awesome! Thanks a lot!
Dude! Thats amazing fr
That is AWESOME Dude!
Awesome!!
The Charlie scream 😂
Nice work, way to stick with it!
Impressive!
Impressive.
I’m interested in how you forked your sim software. Would love to see that video.
This is so cool.
That's super cool man! I love seeing the improvements you made from one version to the next. As far as the oscillation go on your last flight, it seemed like early in the flight the PIDs were too high but later on they seemed close to correct. Would doing some kind of speed dependent PID ramp be a good idea?
Dynamic PID gains would definitely improve flight performance, especially for longer flights!
Awesome ..
Gratz! i hope you can improve to next project with you gained experience.
Very cool!
Nice!
Can you do a video on the control computer? I'm fascinated by them!
Really interested on how you design the flight controller from scratch. If time permits, please do a series on that one.
Ad astra!
Nice
DUDE fuck yeah we love to see it
More 3D plots please 🙏
Sick
you are awesome!
No you!
nice
Very well done! Congrats! Also +respect for STM32 ;)
I noticed Mahony filter mentioned in the code. So you do some sensor fusion? What data is involved besides the gyro?
Would also recommend you to learn DMA and interrupts if you haven't yet. STM32 has amazing peripherals and you can offload so many things on them instead of wasting core cycles. That makes a HUGE difference in performance. As I can see from your code you are doing things like sensor reading in a blocking way (not 100% sure, sorry if you are not, not much code on the screen you know ;) ). That's not only a waste of CPU cycles but you may also have inconsistent time intervals for each "task". Instead, you can use hardware timers to schedule your "tasks" with precise time intervals and do sensor reads in a non-blocking way with DMA + interrupts. With that, you will get even better performance compared to RTOS.
Good luck!
Thanks for your comment! I'm a big fan of your work! I used the Mahony filter to fuse gyro and accel data for orientation during ~1g flight and ground phases. I will definitely be exploring DMA and interrupts in the next project! I'm currently just using Arduino millis to schedule "tasks," but I would like to try out the hardware timers like you suggested. :)
tremendo!
Great Work Man! How did you learn to design the pcb and write firmware could you please explain that too
Next video will be all about this!
This is such a great project! I was also attempting to build my model rocket with a software that displays Real-Time Telemetry, I was wondering if you have any recommendations or references as to that? I want to implement the motion tracking as well as the data, nice video btw :)
Thanks for watching, my next video will be about the flight computer and flight software! In the meantime, I recommend checking out BPS Space and Lafayette Systems if you haven’t already. They have lots of great information regarding real time telemetry!
Very cool project! Any tips on the custom pcb controller development? I’m a mechanical engineering major but one of my personal projects involves building a quadcopter from scratch. Right now I’m using flight controller I made myself that uses an arduino nano and and MPU 6050 IM. One of the improvements I’d like to make is creating my own pcb to integrate my main processor, sensors, and voltage regulation into single package.
Next video will be all about Flight Computer ONE, good luck on your project!
subbed. more content boi.
On da wayy!
What are you using for logging/telemetry/dataviz? It looks nice.
I used RFD900 and Processing Java for telemetry, next video will explain more about this!
What software are you using for real time data plotting and orientation display. It looks awesome
Im using a custom software written in Processing Java, I will explain more about it in the next video!
and....................... subscribed
@KofiAsare0 The good ol' 6050 IMU, nice! Did you pull individual x-y-z axis samples, or use fully-fused result? It would be neat to see you switch to a valved propellant system, to enable Falcon 9-like landings. That a high school graduate is developing his own TVC rockets... the future is looking very bright. Subscribed w/all notifs.
I ended up using a different IMU in Flight Computer ONE V2 & 2.5, more about that will be in the next video!
@@KofiAsare0 Very cool, looking forward to more vids!
I'd like to offer some ideas:
1. Would a Raspberry Pico be cheaper to use?
2. Have you considered using sugar (candy) rocket fuel. Just as much thrust as black powder, you could control the burn length, and, most importantly, it gives a slower lift off than than the black powder based Estes engines. This would give the servo controls more time to correct the flight. Also, cheaper once you have the engine casing.
The pico would be cheaper but lacks some critical peripherals such as an FPU, I'm also quite spooked to pursue custom prop for now lol!
good luck
Dude, that's hot
